Escobar entered the season as Baseball America's 56th-ranked prospect, but has struggled at Triple-A Fresno. He has a 5.11 ERA with 96 strikeouts and 37 walks in 111 innings at Fresno.
Hembree is the only one of the two with major-league experience, as he tossed 7 2/3 scoreless innings for the Giants last year. He has a 3.89 ERA in 39 1/2 innings over 41 appearances for Fresno this season.
Teixeira, who has been out since suffering a lat injury last Sunday, will stretch and run Saturday, according to the Wall Street Journal. He will then try to throw and hit off a tee Sunday, to determine if he has made enough progress from the injury to avoid a trip to the disabled list.
Even in a best-case scenario, the earliest Teixeira might return to action is Monday in Texas.
Encarnacion, who has been out since July 5 with a quad injury, felt a twinge while swinging recently and will be shut down for the next few days. At this point, no set timetable is known for his expected return.
Further details on the trade are not yet known, but numerous reports earlier had indicated talks were heating up. Peavy has disappointed this season with the Red Sox, posting a 4.72 ERA in 124 innings, and has a $15 million player option on his contract for the 2015 season, though it is unlikely to vest, given that he is unlikely to record 400 innings pitched combined between 2013 and 2014.
Pierzynsky was cut by the Red Sox earlier in July, after hitting .254/.286/.348 with four home runs in 72 games.
Kottaras appeared in for games for the Cardinals, picking up one hit in five at-bats.
Gordon went 3 for 5 with two runs scored from the top of the lineup. He added a triple and an RBI, along with a stolen base in the win.
Gordon is hitting the ball well since the All-Star break, raising his season average from .292 to .298 in that span. He is hitting .367 with four multi-hit games in his last seven.
Span put together his second four-hit game in a row Friday, as he went 4 for 5 at the top of the lineup. Span scored once and drove in one run, his second game in a row with an RBI as well.
Span now has seven multi-hit games in his last 10, and is hitting .387/.446/.440 in the month of July.
Ramirez went 2 for 5 in the game before he was pulled for a defensive replacement late. He drove in one run with his eighth-inning single, one of his two singles in the game. He also struck out twice, and scored once.
Ramirez was out of the lineup for four days due to a hand injury. He is hitting .303/.465/.394 in the month of July.
